unit 5 equilibrium kidneys

Question 1

what is the role of the kidneys?

Answer 1

-regulate water, pH, + removing waste

Question 2

Step 1
Filtration:

what happends?

where?

what goes in and what doesn’t?

Answer 2

What: Blood enters the glomerulus through the afferent artery

where: This is inside the bowmans capsulal

Goes in:
water, ions, small nirtients, and waste move into the Nephron

Stays out:
blood cells, plates, + plasma proteins are too big to enter

Question 3

Step 2
Reabsorption pt 1:

Proximal conveluted tubual:

descending and assending loop of henlay;

Answer 3

Proximal conveluted tubeual:
-Fluid from bowmans capsual enetrs proximal conveluted tubeual

Desending loop of henlay:
water, ions, small nirtients, and waste move down the Desending loop of henla

Assending loop of henlay:
-active transport (ion pumps) reabsorb Na+,Cl+, and K+ into surrounding fluid

Question 4

Step 2
Reabsorption pt 2:

distal conveluated tubeual:

collecting duct:

Answer 4

Distal conveluated tubual:
more salts absorbed
——————————————————-

Collecting ducts:
reabsobed more water and some urea to increase concentration gradient

Question 5

step 3
secretion:

Answer 5

when things go into the nephron

to balance acididty
water soluble drugs
ions

Convelluted tubular and collecting duct
